Firmware archive for a Philco PHN 14 laptop, with board references Ph24 and H24l and revision 2.1 given in the name. The package is a 468 KB RAR file, so unpack it and check the image size against the flash chip before use. Such dumps let technicians recover a laptop with corrupted BIOS by programming the SPI chip directly. Match the board marking and revision 2.1 on the PCB, and back up the original chip before writing anything.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
